The Star T Tauri in Variable Nebula NGC 1555: Close-up View | Schulman Telescope

The Star T Tauri in Variable Nebula NGC 1555: Close-up View | Schulman Telescope

NGC 1555 is a variable nebula illuminated by the star T Tauri (yellow-colored star to the right of center in a cocoon of gas and dust), located in the constellation Taurus. Variable nebulae are reflection nebulae that change in brightness because of alterations in their star. NGC 1555, a Herbig–Haro object, is also in the second Sharpless catalog as 238. This nebula was discovered in 1852 by John Russell Hind and explains why it is sometimes known as Hind's Variable Nebula.

Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionized gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometers per second. Herbig–Haro objects are commonly found in star-forming regions, and several are often seen around a single star, aligned with its rotational axis. Most of them lie within about one parsec (3.26 light-years) of the source, although some have been observed several parsecs away.

The Star T Tauri in Nebula NGC 1555 | Mayall Telescope

The Star T Tauri in Nebula NGC 1555 | Mayall Telescope

T Tauri is a famous variable star in the constellation of Taurus. In this image, it is the star at the center, embedded in dust and gas. The nebula itself is known as NGC 1555. T Tauri is a variable star in the constellation Taurus, the prototype of the T Tauri stars. T Tauri is the prototype for a class of stars (known collectively as "T Tau stars") that are notable because they are very young stars in the process of forming. These stars have just recently emerged from the dense dust and gas "cocoons" from which they formed. 

Distance: ~450 light years

The Nicholas U. Mayall Telescope is a four-meter (158 inches) reflector telescope in Arizona named after the American observational astronomer of the same name. The telescope saw first light on February 27, 1973, and was the second-largest in the world at that time.

Extreme Ocean Temperatures are Affecting Florida’s Coral Reefs | NOAA

Extreme Ocean Temperatures are Affecting Florida’s Coral Reefs | NOAA

Since April 2023, the National Oceanic and Atmospheric Administration (NOAA) has been monitoring a steady rise in ocean temperatures, which is resulting in unprecedented heat stress conditions in the Caribbean basin, including waters surrounding Florida and the Gulf of Mexico. On Thursday, August 17, 2023, NOAA scientists provided a briefing on how these record-breaking warm ocean temperatures have stressed, bleached, and in some cases, killed corals within the 3,800 square miles of the Florida Keys National Marine Sanctuary.

Florida Keys National Marine Sanctuary

https://floridakeys.noaa.gov

Florida is a state in the Southeastern region of the United States, bordered to the west by the Gulf of Mexico; Alabama to the northwest; Georgia to the north; the Bahamas and Atlantic Ocean to the east; and the Straits of Florida and Cuba to the south. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean.

Coral reefs are often referred to as the "rainforests of the sea," due to their incredible biodiversity and ecological importance. They provide vital benefits as part of marine ecosystems by sustaining habitats for marine life, buffering the harmful impacts of storms on coastal communities, and supporting local economies through tourism and fishing.

India's Chandrayaan-3 Lunar Lander Mission: First Close-up Moon Images | ISRO

The Indian Space Research Organisation (ISRO) Chandrayaan-3 Lunar Mission captured images of the Moon during Lunar Orbit Insertion (LOI) and after the separation of the lunar lander from the propulsion module. Chandrayaan-3, ISRO’s third lunar exploration mission, consists of a propulsion module, a lander, and a rover. Chandrayaan-3 is planned to land about 70.9 degrees south of the lunar equator. Chandrayaan-3 is India's effort to become the fourth country, after the United States, Russia and China, to successfully soft-land on the Moon. The Chandrayaan-3 spacecraft would also be the first to land at the lunar south pole, an area of special interest for space agencies and private space companies because of the presence of water ice that could support future surface activities.

The Boogeyman Nebula: LDN 1622 in Orion | Schulman Telescope

The Boogeyman Nebula: LDN 1622 in Orion | Schulman Telescope

To some, this dark shape looks like a mythical boogeymana mythical creature used by adults to frighten children into good behavior. Scientifically, Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close in the sky to Barnard's Loop, a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion.

 LDN 1622 is a dark nebula, so called because these dense interstellar clouds of gas and dust blot out light from background objects, appearing as ink-dark clouds against a backdrop of stars. This enigmatic cosmic cloud is 1,300 light-years from Earth in the nearby Orion complex, a star-forming region thronging with young stars and other dark nebulae.

Gravitational Waves: Ripples in Space-Time | Hubble Science | NASA Goddard

Gravitational Waves: Ripples in Space-Time | Hubble Science | NASA Goddard

Gravitational waves are invisible ripples in the fabric of space-time. They are caused by some of the most violent and energetic events in the universe. These include colliding black holes, collapsing stellar cores, merging neutron stars or white dwarf stars, the wobble of neutron stars that are not perfect spheres and possibly even the remnants of gravitational radiation created by the birth of the universe.

In this video, Dr. Padi Boyd explains gravitational waves and how important the Hubble Space Telescope is to exploring the mysteries of the universe.

HD 45166: The Most Magnetic Massive Star Found | Artist’s Animation | ESO

HD 45166: The Most Magnetic Massive Star Found | Artist’s Animation | ESO

This video shows an artist’s animation of HD 45166, a massive star recently discovered to have a powerful magnetic field of 43,000 gauss, the strongest magnetic field ever found in a massive star. Intense winds of particles blowing away from the star are trapped by this magnetic field, enshrouding the star in a gaseous shell as illustrated here.

This finding provides clues to the origin of magnetars, compact dead stars laced with magnetic fields at least a billion times stronger than the one in HD 45166. Astronomers believe that this star will end its life as a magnetar. As it collapses under its own gravity, its magnetic field will strengthen, and the star will eventually become a very compact core with a magnetic field of around 100 trillion gauss—the most powerful type of magnet in the Universe.

HD 45166 is part of a binary system. In the background, we get a glimpse of HD 45166’s companion, a normal blue star that has been found to orbit at a far larger distance than previously reported.

New Type of Massive Magnetic Helium Stars Gives Clues to Magnetars’ Origins | ESO

New Type of Massive Magnetic Helium Stars Gives Clues to Magnetars’ Origins | ESO

ESOcast 264 Light: Using multiple telescopes around the world, including European Southern Observatory (ESO) facilities, researchers have uncovered a living star that is likely to become a magnetar, an ultra-magnetic dead star that is a variant of neutron stars. This video summarizes the discovery. Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers do not know exactly how they form. This finding marks the discovery of a new type of astronomical object—massive magnetic helium stars—and sheds light on the origin of magnetars.

Despite having been observed for over 100 years, the enigmatic nature of the star HD 45166 could not be easily explained by conventional models, and little was known about it beyond the fact that it is one of a pair of stars, is rich in helium and is a few times more massive than our Sun. HD 45166 is located about 3,000 light-years away in the constellation Monoceros (the Unicorn). This star was discovered to have an incredibly strong magnetic field, of 43,000 gauss, making HD 45166 the most magnetic massive helium star found to date.

In a few million years, HD 45166 will explode as a very bright, but not particularly energetic, supernova. During this explosion, its core will contract, trapping and concentrating the star’s already daunting magnetic field lines. The result will be a neutron star with a magnetic field of around 100 trillion gauss—the most powerful type of magnet in the Universe.

Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery.
